Problem

The issue list shows the raw issue type as text (Bug, Story, Sub-task, Epic, …). We're already using symbols for process status indicators (○, ✓). Users are used to recognizing issue types by their icon in Jira, so it would be nice if we could support configuring custom icons per type.

Proposal

Add an optional gui.typeIcons map to the config:

gui:
  typeIcons:
    Bug: "🐞"
    Story: "📖"
    Task: "✅"
    Sub-task: "📎"
    Epic: "⚡"

Unconfigured types keep their full text, so no information is lost, and the feature is opt-in with an empty default.

I have this implemented on a branch and can open a PR.
